This Crazy Computer controlled coffee roaster has been developed by Matthew Williams. The machine is also as strange as its name.
The basic PID of the device is a Fuji PXR4 that can be used with a laptop or a computer via a USB port.
In the roaster a fan is used to control the roast process and the roast chamber is made using bakelite tube and a 3' diameter Glass tube.
For the heat to dissipate without damaging the whole setup Matthew has used a high temperature RTV Silicone.
There is a screen at the bottom of the device that can be used to empty the roaster and get freshly roasted beans for a great cup of coffee on a cool and breezy winter morning.
